How to Choose Memory (RAM) for Your Computer

You need memory for your computer. But how should you choose the right kind? Whether you're upgrading your computer or building a new one, learn now.

Step 1 If you bought your computer from a manufacturer, use a search engine or go to the manufacturer's site to find the specs on your model. The max RAM found in the specs is likely the max RAM the whole system supports. To find the largest size module the system supports, divide the max supported RAM by the number of slots. Also listed in the specs should be the max speed supported and DDR type (listed as DDR, DDR2, or DDR3). Alternatively, instead of max speed and DDR type, the specs may list something like PC# ####, where the "#" is some number. This is just a different way of representing speed and DDR type, and works equally well in finding the right RAM. If you know the largest supported module, max supported speed, and DDR type, skip to the Tips and Warnings section.

  • Step 2
    If you're building a new computer, follow the above step, except search for motherboard model specs rather than computer model specs. If you don't know the model, look for it printed on the board.

  • Step 3
    If you couldn't find your computer's specs, the info wasn't detailed enough, or you have a custom-built computer, go to http://www.gtopala.com/siw-download.html (also in the resources below) and download the freeware SIW. Install and run it. On the left side, under the "Hardware" section, select "Memory."

  • Step 4
    The "Memory Summary" section on the right side shows the maximum amount of memory that can be installed in the system (listed as "Maximum Capacity"), and below that is the number of memory slots (listed as "Memory Slots"). The "Device Locator" sections tell whether or not memory is installed in that slot. To get the largest size module the motherboard supports, divide the "Maximum Capacity" by "Memory Slots." To get the speed and type, look under the "Device Locator" section, for the listing "Memory Type." Write down the PC#-#### part, where "#" is some number. Also for the listing "Speed," write down the value in parenthesis. For example, in 333 MHz (DDR2 667), write down only the (DDR2 667). You now have the largest supported module, RAM speed, and DDR type. You can use either the PC#-#### or the speed and type when searching for RAM.

  • Step 5
  • In Step 4, you found a supported RAM speed, but it may not be the fastest supported. Just to make sure, look to the left side in SIW. Under the "Hardware" section, select "Motherboard." Using this info, go to the manufacturer's site or do a web search, and see if you can find what maximum RAM speed the motherboard supports.

  • Step 6
    If you're building a new computer and need to buy RAM, look up the specs on your motherboard to find out what kind of memory it supports.

  • Step 7
    The RAM you buy should be no larger than the max supported module size, and should match the type and speed supported by the motherboard.

    According to the maintenance manual only 266Mhz Ram can be added to the notebook.
    This would be SDRAM.
    Hope this helps!!

    how to upgrade the RAM


    1Instructions Things You'll Need:
    • Computers Memory
    1. Step 1 Check the owner's manual or motherboard manual to determine if RAM is parity or non-parity. The website of the company you purchased the computer from usually will tell you what kind of memory your computer needs as well.
    2. Step 2 Find out the speed of RAM (for example, 60 nanoseconds).
    3. Step 3 Determine whether the computer uses single in-line memory modules (SIMMs) or dual in-line memory modules (DIMMs).
    4. Step 4 Find out whether the computer uses regular, FPM, EDO, or Synch DRAMor DDR1/DDR2.
    5. Step 5 Determine the number of pins on the motherboard: 30, 72 or 168.
    6. Step 6 Remove the cover from the machine to find the number of open RAM slots. Look for between two and eight same-sized parallel sockets on the main circuit board. Usually at least two of those sockets will contain RAM - ruler-shaped circuit boards with chips on one or both sides.
    7. Step 7 Purchase additional RAM that matches existing memory specifications.
    8. Step 8 See the Related eHow "How to Install RAM" to learn how to put in RAM yourself; you can also get it installed (recommended if you don't feel comfortable opening up your computer case).

    Tips & Warnings
    • You usually have to install SIMMs in pairs.
    • If you don't know how much RAM you have installed currently, check your My Computer properties in Windows or choose About This Macintosh from the Apple menu.

    windows xp sp3 maximum amount of memory


    HI,
    Of course it can be done, your computer can take up to 2BG of ram (memory) and the slots are located inside the computer tower like this >>>>>
    c3aec59.jpeg

    Your motherboard will have 2 slots like in the picture and will take 2 x 1BG (1GB in each slot), just make sure you buy the correct speed and type memory so it's a good idea to take your memory with you when you buy is so there is no mistakes.


    Good luck
